Leak-Free Connection Weld Neck Flange Used For High-Pressure Pipes

Stainless Steel welded neck flanges are designed to be welded onto pipes, providing a secure and leak-free connection.  Its rim has numerous holes drilled into it that enable the flange to be attached to a bolted flange.

 

The flange provides column strength as well as provides reliable stress distribution through the tapered neck, and transfers stress from the flange to the tubing. Therefore, it can reduce the low-cycle fatigue caused by changes to the tube.

 

Welding neck stainless steel flanges are widely used in industries such as oil and gas, chemical, and pharmaceuticals due to their strength, durability, and corrosion resistance.
